Publication number: 20240081903Abstract: Described here are devices, systems, and methods for closing the left atrial appendage. The methods described here utilize a closure device for closing the left atrial appendage and guides or expandable elements with ablation or abrading elements to ablate or abrade the left atrial appendage. In general, these methods include positioning a balloon at least partially within the atrial appendage, positioning a closure assembly of a closure device around an exterior of the atrial appendage, inflating the balloon, partially closing the closure assembly, ablating the interior tissue of the atrial appendage with the inflated balloon, removing the balloon from the atrial appendage, and closing the atrial appendage with the closure assembly.Type: ApplicationFiled: November 20, 2023Publication date: March 14, 2024Applicant: AtriCure, Inc.Inventors: Gregory W. FUNG, Randall J. LEE, Russell PONG, Robert L. CLARK, III, Arnold M. ESCANO

Patent number: 11844526Abstract: Tissue stabilizing devices and methods for stabilizing, and optionally closing, a target tissue, such as the left atrial appendage, generally include an elongate body with a first lumen and a second lumen, a suction tip coupled to the elongate body, and an injection tip coupled to the elongate body proximal of the suction tip. The suction tip may define a suction aperture and the suction aperture may be in fluid communication with the first lumen to apply suction to the target tissue. The injection tip may be in fluid communication with the second lumen to dispense a contrast fluid.Type: GrantFiled: March 27, 2019Date of Patent: December 19, 2023Assignee: AtriCure, Inc.Inventors: Gregory W. Fung, Robert L. Clark, III, Russell A. Seiber, Russell Pong, Arnold M. Escano

Patent number: 11224435Abstract: Closure devices and methods for ligating tissue, such as the left atrial appendage, generally, include an elongate body having a first lumen therethrough, a snare loop assembly, a vacuum tube, and an imaging device. The snare loop assembly may include a snare and a suture loop releasably coupled to the snare and may at least partially extend from a distal end of the elongate body. The vacuum tube may be slidably positioned within the first lumen to extend through the snare loop assembly. The imaging device may be disposed within the lumen of the vacuum tube.Type: GrantFiled: September 22, 2017Date of Patent: January 18, 2022Assignee: SentreHEART LLCInventors: Gregory W. Fung, Robert L. Clark, III, Russell A. Seiber, Russell Pong, Arnold M. Escano

Patent number: 11207073Abstract: Described here are closure devices and methods for ligating tissue, such as the left atrial appendage. The closure devices may comprise a snare loop assembly comprising a snare and a suture loop releasably attached thereto. The snare may be releasable from an elongate body of the closure device. In some instances, the closure device may comprise one or more markers to allow a user to determine whether the snare loop assembly is twisted.Type: GrantFiled: February 6, 2019Date of Patent: December 28, 2021Assignee: SentreHEART LLCInventors: Robert L. Clark, III, Gregory W. Fung, Russell Pong, Arnold M. Escano, Greg Liu

Patent number: 10959734Abstract: Described herein are tissue closure devices and methods for ligating a target tissue, such as the left atrial appendage. The tissue closure devices may have an elongate body, a snare at least partially housed within the elongate body, a suture at least partially housed within the elongate body, and a tightening element coupled to the suture. The suture may have a suture loop, and the tightening element may be configured to decrease the size of the suture loop when the area of a tissue within the suture loop decreases.Type: GrantFiled: October 2, 2018Date of Patent: March 30, 2021Assignee: SentreHEART LLCInventors: Gregory W. Fung, Alan L. Bradley, Russell Pong, Robert L. Clark, III, Arnold M. Escano

Patent number: 10716571Abstract: Surgical and percutaneous devices for closing tissue, for example, the left atrial appendage, may have an elongate body with a stiffened proximal portion, a flexible middle portion, a distal portion, a closure element with a loop having a continuous aperture therethrough, and a suture loop. The closure devices may have a malleable member attached to the elongate body that may be configured to retain a curve after a force is applied to the malleable member. System and methods for closing the left atrial appendage may utilize a closure device and a curved guide device, and the closure device and curved guide device may be self-orienting.Type: GrantFiled: March 23, 2018Date of Patent: July 21, 2020Assignee: SENTREHEART LLCInventors: Gregory W.
